@RicaNeaga, i have need for some componets eg net4 and some runtimes, which needs restart before properly work. And whole setup process is done in 2-steps, instead of 3 where and frst logon much more faster. I think is better to sacrifice speed to 2 step of installation instead first logon after oobe, and it's look more cosmetic. Current Runonce mode should stay, but svcpack will be great too, and only as switchless installer, not need for true mode. @OnePiece, I know for your application, and i use it for a while with great experience, it's really nice, but i am now pleased with Windows 7 Toolkit because it's completely AIO soultion and it's attached with SoLoR updates it's pretty easy, supports wider formats...
